LOS ANGELES — Strong winds Wednesday caused additional power outages for Los Angeles Department of Water and Power customers, but the number of customers without power dropped to approximately 11,000.

Since the start of the high winds Tuesday afternoon, crews had restored power to over 77,000 customers who were knocked offline, according to a statement from the LADWP. As of 9:30 p.m. Wednesday, nearly 11,000 out of 1.5 million customers served by the utility were without power.

“We want to assure all remaining affected customers that crews will work around the clock until every customer has their power back on,” the statement said.

Customers were advised to expect to be without power for between 12 to 24 hours. Some outages could be restored much quicker, while others may take longer, the DWP said.

DWP representative Sylvia Beltran said that it is crucial for repair crews to determine the cause of an outage affecting a particular circuit before attempting to restore electrical service.

When a crew encounters a downed power line, the parameters of that repair are self-evident, Beltran said. However, circuits can shut down for various other reasons, and the cause must be diagnosed before a crew can re- energize the circuit safely in order to prevent creating further damage, she said.

Downed trees were reported throughout the region, including one that affected power on Lookout Mountain Avenue between Laurel Canyon Boulevard and Horseshoe Canyon Road. A tree fell onto an apartment building in the 500 block of Felton Avenue in Westwood, damaging the roof of the building, but not forcing any residents to evacuate.
